the Flash array end address
The Flash array addresses covered by these protectable regions are shown in Figure 20-3Figure 20-4.
higher address area is mainly targeted to hold the boot loader code since it covers the vector space.
lower address area can be used for EEPROM emulation in an MCU without an EEPROM module since it
can be left unprotected while the remaining addresses are protected from program or erase.
protection settings as well as security information that allows the MCU to restrict access to the Flash
module are stored in the Flash configuration field described in
